Blueberry SIGNAL.jack2rca BB-004
High-quality OFC jack cable with PE insulation, dual shielding, PVC/cotton jacket, and gold-plated 3.5 mm plugs for clear, interference-free analog stereo transmission.
Product Overview
The Blueberry SIGNAL.jack2rca BB-004 is a high-quality stereo audio cable for analog connections between devices with 3.5 mm jack ports.
The fine-stranded OFC inner conductors ensure precise signal routing and clean channel separation.
The PE insulation stabilizes the electrical structure and ensures low-loss transmission.
A double shield consisting of aluminum foil and tinned copper braid reliably protects against electromagnetic and high-frequency interference.
The robust PVC jacket with a blue-black cotton braid ensures flexibility, mechanical stability, and long durability.
The gold-plated 3.5 mm jack plugs in pearl white or silver metal housings are direction-marked and offer a corrosion-resistant connection.
In terms of sound, the cable impresses with clean mids, clear highs, and a balanced stereo stage. Ideal for portable audio devices and compact HiFi systems.
Technical Construction
Each of the two inner conductors consists of 19 × Ø 0.127 mm OFC copper strands, precisely twisted for stable power and signal transmission.
The PE insulation with Ø 1.8 mm reduces capacitive losses and keeps the conductor geometry constant.
A primary protective layer of aluminum and paper foil stabilizes the internal structure.
The overlying TC copper braid with 128 wires provides effective shielding.
The PVC outer jacket (Ø 6.0 mm) is reinforced by a tightly woven cotton braid.
Signal Purity & Sound
The OFC conductor delivers natural, neutral sound reproduction with clear mids and fine highs.
The dual-layer shielding minimizes interference and preserves dynamics as well as detail resolution.
The cable ensures clean stereo images and precise localization, even in environments with higher signal load.
Mechanical Stability
Due to the combination of PE insulation, PVC jacket, and cotton fabric, the cable remains flexible, kink-resistant, and mechanically stable.
The gold-plated metal plugs offer long-lasting contact quality and a firm fit.
The arrow marking facilitates correct installation.
